@nungnum wait wait wait... are you asking permission to play permission? I don't know what to say to that. I feel like, just psychologically, it would be best for you to play a deck with 4x Cavern of Souls for a little while you work this out.

If I run permission as far as strictly speaking counterspells, I run 8-12 depending on the build....typically 10. I have other answer cards and general disruption, so if you count that as permission, the number is probably closer to 15.

I typically pilot Draw-Go decks. So, I run about 10-15 permission/control slots.
If I run a combo deck like, say, Ad Nauseam, then I run 4-8 discard spells and zero-2 counterspells(Flusterstorm)
If your meta is all aggro, I'd suggest more board control less permission.
